GUARD FOR HAT-FINS.

Specification of Letters Patent.

Patented Sept. 30,1913.

Application filed December 18, 1912. Serial No. 737,479.

To all whom it may concern:

Be it known that I, ERNEST H. MANTLE, a citizen of the United States of America, residing at McKees Rocks, in the county of irllegheny and State of Fennsylvania, have invented certain new and useful Improvements in Guards for Hat-Pins, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a guard for hat pins, and the objects of my invention, are, first, to provide a simple and inexpensive device that can be easily and quickly mounted upon the pointed end of a pin toprevent the pin from becoming accidentally displaced relatively to a hat, scarf or other piece of material in which it is mounted; second, to provide a guard for hat pins that will prevent pedestrians and others from being injured by contacting with the same, and third, to accomplish the'above results by a mechanical construction, that is durable and susceptible to'any desired ornamentation.

lVith the above and other objects in view the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is a side elevation of a guard in accordance with this invention, Fig. 2 is an enlarged longitudinal sectional view of the same, Fig. 3 is a plan of the guard, Fig. 4 is a horizontal sectional View taken on the line IVIV of Fig. 2, and Fig. 5 is a similar view taken on the line V-V of Fig. 2.

A guard in accordance with this invention comprises two semi-cylindrical members 1 and 2 having the inner sides thereof, at the inner ends provided with teeth 3 adapted to frictionally engage the pointed end of a pin 4. The outer ends of the members 1 and 2 are flared to provide head sections 5 and 6,- the edges of the section 6 fitting within the edges of the section 5, thereby forming a head that is substantially conical or tapering in elevation. the ends thereof has apertured lugs 7 connected by pins 8 to the sides of the member 1, as shown in Figs. 1 and 5. V

The member 2' intermediate 7 Arranged in the head sections 5 and 6 is a horizontal spiral spring 9 that has one end thereof soldered or otherwise connected, as at 10 to the head section 5 and the opposite end thereof extending between parallel inwardly projecting lugs 11, carried by the inner side of the head section 6. Thetension of this spring is sufficient to hold the inner toothed ends of the members 1 and 2 in engagement with the pin 4 to prevent the guard from being accidentally displaced.

The type of spring used within the guard does not interfere with the insertion of a pin therein and the shape of the head sections prevents the pointed end of the pin from inj uring a person that'contacts with the guard.

One embodiment of the invention has been illustrated, but it is to be understood that the structuralv elements are susceptible to such modifications and variations as fall within the scope of the appended claim.

What I claim is A guard for hat pins comprising a pair of elongated semi-cylindrical members, one nesting within the other and each having its inner face'for a portion of its length at its inner end provided with teeth to frictionally engage the shank of a pin, outwardly tapering semicylindrical head sections integral with the outer termini of said members and one nesting within the other, the outer termini of said head sections being closed, the head section of smaller radius having its inner face in proximity to its closed end provided with a pair of inwardly projecting lugs, a horizontally disposed spiral band spring having its outer end fixed to the inner face of that head section of larger radius and having its inner end and outer spiral loosely supported between said lugs and constituting means for maintaining said members in gripping engagement with the shank of a pin, and means for pivotally connecting the inner termini of said heads together.

In testimony whereof I afiiX my signature in the presence of two witnesses.
